Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
In the present invention, one or more fixedly programme attributes according to program, the program that this attribute is identical among the EPG is made like-identified, when the user need understand when having other programs of certain same alike result with selected program, can in EPG, search for according to this program identification and obtain, thereby avoided needing manually to browse the situation of whole EPG in the past, not only saved the time, and the user understand comparatively convenient, easily.
Fig. 1 shows the implementing procedure of the broadcasting method of Digital Television EPG provided by the invention, and details are as follows:
In step S101,, all programs in the electronic program guide (EPG) are identified, and the identical program of this programme attribute is made same program identification according to fixing programme attribute.
As embodiments of the invention, programme attribute can be programm name, featured performer, director, reproduction time etc.
As embodiments of the invention, can adopt numeral that program is identified.Certainly, also can adopt the sign of forms such as character or character string.
In actual mechanical process, can be according to one or more programme attributes, the program of EPG is identified, be called example with name below according to program, the program of five channels among the sign EPG, as follows:
In step S102, EPG and program identification be loaded in the TS stream broadcast.
As embodiments of the invention, this program identification can be carried in Event Information Table in the TS stream (EventInformation Table, EIT) in, for example, can in the EIT table, increase the sign descriptor and describe program identification.
As shown in the table, be the form of sign descriptor:
| Grammer figure place memonic symbol |
| mark_correlation_descriptor(){ descriptor_tag 8 uimsbf descriptor_length 8 uimsbf for(i＝0；i<N；i++){ search_type 8 uimsbf search_correlation 16 uimsbf } } |
As another embodiment of the present invention, program identification can be broken into packet separately, be carried in the TS stream as private data, broadcast.
Fig. 2 shows the implementing procedure of the inspection method of Digital Television EPG provided by the invention, and details are as follows:
In step S201, from TS stream, parse EPG and program identification.
When program identification is carried in the EIT table, from TS stream, parse the EIT table, can resolve according to the sign descriptor in the EIT table and obtain program identification.
When program identification breaks into packet separately, during as private data, receive private data, from private data, parse program identification.
In step S202, the program receiving selection instruction.
For example, the user views CCTV1's the program of " news hookup ", check if desired whether other channels play this program, when perhaps whether other periods of this channel also play this program, just can send the program selection instruction, to choose this " news hookup " program by input units such as remote controllers.
In step S203, the search program identification is the program of p in EPG, and shows that this program identification is the programme information of the program of P.Wherein, the program identification of the program chosen for the program selection instruction of p.
In order to improve search efficiency, as embodiments of the invention, can be according to the program identification p of selected program, the search program identification is the event_id of the program of p, thereby just can find corresponding program according to this event_id, and can show the programme information of the program that this is corresponding.
The project that this programme information can comprise for EPG, for example information such as channel, programm name, reproduction time, featured performer.
Fig. 3 shows the structure of the broadcasting system of Digital Television EPG provided by the invention, and this system can be software unit or hardware cell or the unit soft, that scleroma is closed that is built in digital TV front-end server.
The program identification unit 31 of this system is according to fixing programme attribute, all programs in the electronic program guide (EPG) are identified, and should make same sign by fixing identical program of programme attribute, and load and broadcast unit 32 and EPG and program identification are loaded in the TS stream broadcast.
Fig. 4 shows the structure of the system of checking of Digital Television EPG provided by the invention, this system can be software unit or hardware cell or the unit soft, that scleroma is closed that is built in receiving terminal for digital television.
The resolution unit 41 of this system parses program identification and EPG from TS stream, program selection instruction receiving element 43 program receiving selection instructions, program searching display unit 45 Search Flags in EPG is the program of p, and shows that this program identification is the programme information of the program of P.Wherein, the program identification of the program chosen for the program selection instruction of p.
This program searching display unit 45 Search Flags in EPG is the program of p, and the process that shows the programme information of the program that this is designated P can be the event_id of the program of p for: event searching module 451 search program identifications, programme information display module 452 finds corresponding program according to the event_id of program, and shows the programme information of the program that this is corresponding.
In sum, in the present invention, one or more fixedly programme attributes according to program, the program that this attribute is identical among the EPG is made like-identified, when the user need understand when having other programs of certain same alike result with selected program, can in EPG, search for according to this program identification to obtain, thereby avoid needing manually to browse the situation of whole EPG in the past, not only saved the time, and the user understand comparatively convenient, easily.Utilize numeral to identify program, thereby make according to the efficient of the search of program identification in EPG highlyer, and require lower for the hardware configuration of receiving terminal for digital television.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
